Here is Stephen Batchelor's website. Batchelor was a Tibetan monk for six years and a Korean Zen monk for four. He is an excellent teacher, and one of the greatest influences on my thinking as a Buddhist. He has some awesome podcast links. Definitely check this out!

Upaya Zen Center has hundreds of great audios from teachers of various lineages.

San Francisco Zen Center is a great resource for Dharma talks as well. Some are better than others; see for yourself. You can also find them on iTunes. Click here for some sesshin lectures from Shunryu Suzuki Roshi--they're great, and free.
